ABSTRACT:
The invention in question is a repairing machine, which is suited to repairing damaged conduits which are inaccessible for repair work. This repairing machine is remote-controlled and monitored with television cameras. At the head of the driving carriage, various devices, which are necessary for the repairs, can be attached to a motor-driven rotatable toolhead. A simple construction of the movable head has made it possible to accomplish all of the necessary movements with uncomplicated mechanics, and at the same time, to forego a tedious slide coupling for the control lines without letting them get tangled with the device. Therefore, with this invention, the production costs for the whole device could be lowered and, likewise, the proneness to repairs could be reduced.
